T0 oli '1e/mm. it may concern:

Be it known that I, CHARLES Loonwoon, a citizen of the United States, resid inloT :it 28S) Market street, Newark, county of Essex. and Stilte of New Jersey, have i1ivented certain nevi*v and useful Improve-- ments in Pressed-Steel l-langer-Boxes, fully described :ind represented in the following eution and the :uoorupanying drevvfs, forming ii part of the same.

The object of this invention is to furnish :i cheap and strong construction for e rollerbeering hanger-box wherein the 'parte may he unide- Wholly of sheetinetzil drawn or pressed to shape, and the box may be provided with opposite parallel hangenguides adopted to `guide the box between the cheeks of the hunger. lVith this construction, the shell of the hunger-box is formed of eveylirdrivel drawn steel tube the inner Wall et which is .smooth enough, 'without any inish. to support the rolls in their rotation around the shaft or axle Whieh if; supported in the box,

The opposite hanger-guides are fornied upon n sheet-metal saddle pressed into'sueh shape :is to forni seats upon the upper and lower sides ot' the box with sockets to re vive the points of edjustingserews. braces; projected from the seats toward the opposite ends of the shell l(ind wings projected from the sides of the seats toward the .center line el the shell where they Contact with one :mother und with theshell. The saddles are seiured te the Shell byleotrie. Spot-Weide or h v riveting'. coller bent inwardly Upon one end of the shell and a sheet-steel cap 'forming it similar coller is pressed ele sv tic-,illy upon the opposite end, l/Vith this consti-mation, :i single sheet.steel tube from. the entire body of the box as well as the cylindrical seat within which the rolls revolve, and such shell requires ne casing or exterior support other than that alorder by the. saddles.

Springnvipers may be inserted in the bottom ol the shell :it its opposite ende to press upon the shaft or axle, :ind wipe oil any lubrirnnt. and thus prevent it from exuding at the` 1;.1 of the box. Such Wipers require no :idjhsstment when in use, nor any pijojections upon the outer` Sides of the box.

The wipers are supported inovably in Secured to the Specification of Letters Patent.

The invention 1svill be understood by ref- 60 erenee to the annexed draWing,'in Whichf Figure 1 is e plan of the harlgerfbox'with sections of the hanger-legs which foim the cheeks between which the hanger-box is rnovably supported; Fig. 2 is eperspective 65 View of the can for one end of the' sleeve; Fig. 3 is an elevation of the box, the right hand end showing the exterior of the box; and the lett-hand end Showing the shell and saddles in section; Fig'. 4 is o. cross section 7C at the center line of the box; Fig, 5 is 'e side view of one of `the Saddles detached from the box; and Fig. V6 is an end View of the box; and Fig. 7 shows the saddle made in one piece.

a designates the shell, formed offizA cylin`- drieal drawn steel-tube with elcolli bspun inwardly Upon one eiid. At thej'opposite end the cap is provided with-e. simila''eoller'c l.ind cylindrical flange d which lits tightly- 8.0 over the end of the shell'so as to be pressed thereon and held by friction. l

A. set of rolls e carried by u. cage e" is fitted to revolve in Contact with the inner Wall" of the shell and with guards inside the shell. "S in forming the saddles by stamping from sheet-steel. it can embrace the vvhole, or only l one-half of the shell, and each side is conf struotedwith e central seat g having a socket h in the middle to receive the point of angle?" adjusting screw h, with integral braces 2 projected from the seat toward the opposit/e` ends of the shell and having cylindrical 'cidre viture to ht the seme, and with Wings bent', l' to fit the opposite sides of the-shelland to Contact with the shell and preferably onel another, upon its center line. "1`l'1ezs'gtcl-H die when thus adjusted upon the shell'i's secured thereto by rivets or by spot-welds' effected electrically at the points marked Z. 100,

Spotovelds are preferable, as the inner surface or the shell must be kept entirely smooth to forni a cylindrical seat for the rolls. and the of rivets would necessitate perforation of the shell and the hammering` of the rivete.y whereas spot-Welds dof-not cause any perforation nor deform the shell.` in any wey.

-fis indicated in Fig. i,

By forming the saddle of pressed sheet steel it is mede lighter cheaper than eesthieoi. :wid notl only es e more accurate form ont mush greets-r strength then oastdnetel of the seme wei sind such saddles are remlilyseeured to the shell Without performing the lutter.J by Welding there to et vario-us points by an electric current, applied through electrodes upon the inner side of the shell and upon the outer side of the saddle. The shell thus possesses en unbroken cylindrical Wall upon its interior which is well adopted to support the rolls as they rotate about the shaft.

The Wipers, to @Online the lubsicent to the shell, are shown lialoeks o fitted to move radially in sooiets which are secured by Welding, or otl'iervvises to the collars and c at the ends of the shell, and each socket has segmental guard .j attached to its linner side which serves es a guide for the cage e, and thus holds the set of rolls from longitudinal movement in the shell.

The vvipebbloolfs o are pressed eonstantly toward the shaft .sj by springs w Within the sockets p, and A'operate to wipe oil' any oil that moves toverd lthe end ot the shell and thus confine it therein.

By attaching one of the wipex's end gum-ds q to the oep, it is removable from the shell 'with the cap, so that the'y rolls and their cage omi be inserted Within the box, and thereafter held in place by such removable guard.

if desired. the saddle may be made in one pie-3e of shee'ometal` as shown in Fig. 7', with the seats stemped thereon, the wings-1', curved to tit the shell ad und the henger- `guides also stamped to fit the outside of the shell. the wholeheing Capable of bending :it four places mul-iced 25 il, 4, so as to our breee the entire eircunferenee of the shell.

The construction described herein is esn peoially adapted for luse in ceses where the shaft van be inserted in the box, or the box slid open the end of the shaft longitudinally.

lWhere the shell .is formed of en unbrokem Cylinder. it has much greater strength than' :i divided shell, and the use oi lguides and fes tenings for holding divided parts together Wl'ie' in use is Wholly avoided..

Heiwerfhoxes for sin, use een, by this construction, he mede very eheeplyg and per Aguides contacting with t feetly adapted to the uses of e roller-bear- Heving thus set forth the nature of the invention what is claimed herein is:

l. A, pressed sheet-metal hanger-box having e shell consisting of e cylindrical undi vided drawn steel tube7 pressed sheet-metal saddles secured upon its opposite sides and shaped to forni opposite parallel hangereuides. :md a. set of rolls fitted to revolve upon the inner wall of such shell.

A pressed sheet-1netal hanger-box havroll-supporing shell consisting of a cylindrical undivided drawn tube with pressed sheet-metal saddles fitted to its upper und lower sides and formed with parallei hanger-guides nt o posite sides, such lie shell at its oppo site sides and attached thereto by suitable lmeans, and a set of rolls fitted to turn upon the inner wall of such shell.

`:i central seat having a socket to receive an.

adjusting-screw, integral braces projected from such seats toward the opposite ends of the shell, and integral side wings projected from such seats and forming parallel guides et opposite sides of the shell, such saddles being secured to the shell by suitable means.

4. A pressed steel hanger-box having a roll-supporting shell consisting of a cylindrical undivided'drawn steel tube with. :i collar bent inwardly et one end and having n pressed steel cap fitted elastically upon the opposite end, sheet-metal sockets for spring oil-wipers secured Within the ends of the shell by spot-vvelds7 spring Wiper-blocks fitted movebly to such sockets, und sheetmetal saddles fitted to the upper and lower sides of the shell and secured thereto by spot-Welds so as to form no break in the bearing-surface for the rolls.

' 5. A pressed steel hunger-box, having a rollsupportingr shell consisting of a cylindrical undivided drawn steel tube provided with o, saddle formed in one piece of sheetmeiel with parallel hanger-guides at oppo siteysidesy and such guides contacting with the shell at opposite sides and secured thereto by suitable means.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
